An arrangement and an implant are provided for increasing the stress resistance of the implant arranged in an upper jaw bone (1). The implant has access via parts (9, 4') to the sinus cavity (5). At said parts, the implant is arranged with a convex or rounded front surface which, upon access, lifts the sinus mucous membrane, without piercing the latter, and thus forms a closed space (7) between the parts and the underside of the mucous membrane. The implant is provided, at least at said parts, with growth-stimulating substance or substances (15) which interact with cell-containing body fluid (8) which penetrates or has penetrated into the space, so that new bone (11) is formed around said parts of the implant.
L'invention concerne un dispositif et un implant. Le dispositif permet d'augmenter la résistance à la contrainte de l'implant disposé dans une maxillaire supérieure (1). Cet implant comprend des parties traversantes d'accès (4, 4') au sinus (5). Au niveau desdites parties, l'implant est conçu de manière qu'il présente une surface antérieure convexe ou arrondie qui, lors de l'accès, soulève la muqueuse du sinus, sans pour autant la percer, formant ainsi un espace fermé (7) entre lesdites parties et la face inférieure de la muqueuse. L'implant comprend, au moins auxdites parties, une ou plusieurs substances stimulatrices de croissance (15) qui interagissent avec un fluide corporel contenant des cellules (8), lequel pénètre ou a pénétré dans l'espace, de façon que le nouvel os (11) se forme autour desdites parties de l'implant.
